To all whom it may concern Be it known that I, ROY D. CURTIS, a citizenof the United States, residing at San Diego, in the county of San DiegoandState- Another object of importance'resides in the construction ofthe parts which cooperate to force the bristle heads into effectiveengagement with the walls of a pocket formed in the stock of the brushinto which they are adapted to be fitted, while. associating the parts,with a View of facilitat ing this operation, together with a novelmanner of locking the bristle heads as a unit in the pocket.

Other objects will appear as the nature of the invention is betterunderstood from the following description, the invention residing in theconstruction, combination and arrangement of parts hereinafter set forthin detail. v

In the drawing forming part of this application like numerals ofreference indicate similar parts in the several views and wherein:

Figure 1 is a longitudinal sectional View through the brush constructedin accordance with myinvention. Fig. 2 is a top plan view with thebristles removed. Fig. 3 is a top plan View of the stock of the brush.Fig. 1 is a perspective view of the bristle heads assembled. Fig. 5 is abottom plan view thereof. Fig. 6 is a view showing the manner ofspreading the bristle heads for cleaning the same. Fig. 7 is aperspective view of one of the bristle head sections.

Referring more particularly to the drawing A designates generally abrush constructed in accordance with my invention, it

being understood that any suitablematerial may be employed in theproduction of the brush, and that the latter may vary in form anddimensions.

The handle of the brush is indicated at 5 and the head or stock shown at6,the latter having'its'upper' surface recessed to provide a MSTATESPATENTEOFFICE;

pocket 7 in which the bristle heads "are adapted to be removably fitted.The front end wall ofthe'po'cket is forwardly beveled j as at 8, whilethe rear end wall is oppositely beveled as at 9 for a portion'ofitsheight,

and then out rearwardly 'toprovide a shoulder10.'v

The bristle head as a unit comprisesa plurality of. elongated flatstrips 11 pivotally mounted upon-the rod "12, the bristles. 13 beingfastened ther'eto'in anywell known manner employed by brushmanufacturers.

The forwardend of each strip is provided j with 'a'projection 16 havingits under sur-" face beveled as at '17 to provide an inclined surface 18when thestrips are assembled as shownin Fig. 4. The inclined surface 19is adapted to cooperate with the beveled end wall 9 of the pocket 7 oninsertion of the bristle head as a unit therein, so as to force thebrlstle head forwardly into effective en gagement with the front endwall 8 of the I projections 16 in alinement with the shoulder 12. Passedtransversely through an open.- ing in oneside wall of the pocket 7 is akey 20 of rectangular formation in cross section adapted to be seatedupon the shoulder 12 and the projections 16 to retain the bristle headas a unit positioned within the pocket 7, the free end of the key beingreceived within a suitable recess in the opposite side wall of thepocket 7, and having its opposite end projecting a slight distance topermit the same to be grasped when it is desired to remove the bristleheads from the brush for any purpose whatever.

By reason of the construction hereinabove described, it will be manifestthat the bristleheadsare not only effectively held in position withinthe stock of the brush, but that the same may be readily removed, andthat both the stock and bristle heads may be independently cleaned whendesired with a view of maintaining the brush in a sanitary condition.

It. is believed that from the foregoing description, the nature andadvantages of the invention will be thoroughly understood withoutrequiring a more extended explanation and therefore the same has beenomitted. What is claimed is v 1. A brush including a head recessed toprovide a pocket, the end walls of said pocket-being oppositely beveled,a bristle head removably fitted Within said pocket and" constructed tocooperate with one of saidend Walls for moving said bristle head intoengagement With the opposite end Wall, and means for locking said partsoperatively associated.

2. A brush including a head recessed to provide a pocket, the end Wallsof said pocket being oppositely beveled, a" bristle head removablyfitted in .saidpocket and comprising a plurality of separate pivotallymounted sections, each ofsaid sections being constructed to cooperateWith one of said end Walls for moving said bristle head as a unit intoengagement With the opposite end Wall, and means for locking the partsoperatlvely associated.

3. A brush including a head recessed to provide a pocket having one endWall provided wlth a shoulder, a bristle head removably fitted Withinthe pocket and compris ing a plurality of separate pivotally mountedsections, each of said sections being formed with a projection at oneend adaptedto lie flush With said shoulder, and a transverse key passedthrough said pocket above said projections and shoulder for andpivotally mounted sections, each of said secj holding the-bristle headpositioned within the pocket.

4:. A brush including a head recessed to providepocket, the end Walls ofsaid pocket being oppositely beveled, a shoulder formed by one of saidend Walls, a bristle head removably fitted Within said pocket comprisinga plurality of separate V v ROY D. CURTIS. Witnesses: I
